Isidro Fernando Hernandez-Ortiz, known as Isidro Ortiz, was 23 when he was shot and killed the morning of November 1, 2020, in a remote desert area off the 2500 block of East Aerospace Parkway on Tucson’s south side near the airport. Police were called shortly before 6 a.m. for reports of gunfire and, after being directed farther into the desert, found Isidro and a woman with gunshot wounds; Isidro was pronounced dead at Banner University Medical Center and the woman’s injuries were described as not life-threatening.

Detectives later learned two other shooting victims had been taken to a different hospital by friends. One of those men, Oscar Daniel Dicochea, was also pronounced dead; a second man survived with non-life-threatening injuries. Investigators say a gathering of roughly 50 people in the desert turned violent when two groups got into a physical confrontation that escalated to an exchange of gunfire. Officers reported multiple shots fired and several vehicles fleeing the scene, and investigators have not specified how many shooters were involved or who fired the fatal shots.

The case is being treated as a homicide investigation. Online remembrances describe Isidro as funny and outgoing, a South Gate Academy attendee and a father. No arrests or suspects have been publicly announced; anyone with information is asked to come forward. Was anyone at that gathering or its vicinity who can help piece together what happened?
